Platform Overviews
Supabase
Supabase is an open-source Firebase alternative built on Postgres, bundling a database, authentication, storage, and real-time subscriptions into one developer platform — widely adopted because it gives teams a full Postgres database (rather than Firebase's NoSQL model) with a similarly fast setup experience. Our engine detects Supabase through 2 script patterns, 2 HTML patterns, and 1 CDN domain tied to its client SDK's API-request conventions and asset delivery. Supabase can be self-hosted or used via its managed cloud; detection doesn't distinguish between the two. Documented at supabase.com.
PlanetScale
PlanetScale is a serverless MySQL platform built on Vitess (the database-sharding technology originally built at YouTube), offering non-blocking schema migrations via database branching — used by teams that want MySQL's ecosystem compatibility with a modern, horizontally scalable managed backend. Our engine detects PlanetScale through 1 script pattern and 1 HTML pattern tied to its client-tooling conventions; like most managed databases its footprint is primarily backend-side with minimal front-end signal.

Key Differences
- Both Supabase and PlanetScale are classified as Database tools, making them the most direct competitors in this comparison.
- Supabase scores higher on AI involvement (10/100 vs 10/100 for PlanetScale), meaning it relies more heavily on AI for site generation and content creation.
- Our detection engine identifies Supabase using 5 fingerprint patterns and PlanetScale using 2 patterns — more signals generally means more reliable detection.
